my only question is: do you belive Switch will outsell Vita or not?
I am just joking! I belive it! It will very soon or may already has outsold Vita. As I once said: "I believe in Nintendo".
Outselling PS4 is the mystery that will unfold with time. I think that it can, by a large margin, but will it? I don´t know and I believe that I don´t have to know. In that case it would be guessing and not believing.
